This study focuses on sensor-based, real-time condition assessment of buildings during and after multi-hazard emergencies and it is based on the idea that; the spatial distribution of damage in a building can be monitored by the help of different types of sensors. The number and locations of these sensors are arranged in such a way that it becomes possible to picture the current condition of the building. Sensors utilized in this study can be listed as accelerometer, ultrasonic range finder, gyroscope, closed cable circuit and video camera. The first step of the research is to decide on the number and location of different sensors that will be deployed inside the building. The next step is to correlate the readings of each type of sensor with the observed damage caused by the disaster. This is achieved by conducting real-time experiments on a scaled corridor model, equipped with sensors. Finally, sensor fusion is carried out, and obtained sensor readings are gathered to provide overall information about the current condition of the building. A decision tree approach is developed, which predicts the penalty scores for blockage in certain regions of the building. By conducting experiments, the developed decision tree approach is validated. Consequently, it is concluded that the obtained information can be used as an input for shortest path algorithms that calculate safe and rapid evacuation paths for the victims in damaged buildings.

Fuzzy Structural Equation Model to Assess Construction Site Safety Performance
Gunduz, Murat; Birgönül, Mustafa Talat; Ozdemir, Mustafa (American Society of Civil Engineers (ASCE), 2017-04-01)
The main goal of this study is to examine the relationships between determinants of safety performance of construction sites. To achieve this goal, 168 observable variables and 16 latent dimensions that affect safety performance of construction sites were collected through extensive literature reviews, expert opinions, and face-to-face interviews. A questionnaire form was developed and administered to construction professionals as a data-collection tool about the observable variables and latent dimensions. ...
Assessing the airtightness performance of container-like buildings in relation to its effect on energy efficiency
Bekboliev, Mirbek; Tanyer, Ali Murat; Department of Building Science in Architecture (2015)
This study analyzes the effect of airtightness on the energy efficiency of single and adjacent containerized buildings, before and after refurbishment. It further gives an overview of air leakage problems found in the sample of prefabricated buildings manufactured and located in Turkey. The air leakage of standard container-like building depends on a number of factors like the age of the building, manufacturing quality and quality of assembly implementation. The airtightness of four typical containerized bu...
ANALYZING THE RELATIONSHIP BETWEEN DISASTER RISK MITIGATION AND URBAN PLANNING PROCESSES: THE CASE STUDY OF ESKISEHIR CITY
Sert Özkiremitçi, Merve; Balaban, Osman; Department of City and Regional Planning (2022-5-11)
The aim of this study is to discuss the effectiveness and efficiency of urban planning in reducing the risk of natural disasters in cities and to analyse the relationship between planning and disaster mitigation processes. The study focuses particularly on the analysis of Eskişehir case with reference to data and information on disaster risk analysis, existing urban development plans as well as the plan implementation processes. After the 1999 Gölcük and Düzce Earthquakes, Eskişehir has also faced and to a ...
A case study for probabilistic seismic risk assessment of earthquake-prone old urban centers
Altindal, Abdullah; Karim Zadeh Naghshineh, Shaghayegh; Erberik, Murat Altuğ; Askan Gündoğan, Ayşegül; ANIL, ÖZGÜR; KOÇKAR, MUSTAFA KEREM; ŞAHMARAN, MUSTAFA (2021-01-01)
The study focuses on the probabilistic seismic risk assessment of earthquake prone old urban centers. This issue becomes even more complex if the considered area is a highly populated, cultural or commercial center. Hence it is an important task to estimate regional earthquake losses and to develop strategies for earthquake mitigation through seismic risk prioritization among such vulnerable populated old urban areas. For this purpose, a sub-district with six neighborhoods in Beyoglu, Istanbul has been sele...
COMPARATIVE ASSESSMENT OF THE SEISMIC PERFORMANCE OF FIXED BASE AND ROCKING BUILDING FRAMES EQUIPPED WITH AN ENERGY DISSIPATION SYSTEM
Özen, Hazal; Dicleli, Murat; Department of Engineering Sciences (2023-3-06)
In this study, the effect of columns with a rocking-base isolation system on enhancing the seismic performance of a reinforced concrete building is investigated. A compara- tive study comprising of comparisons of fixed-based and rocking-based systems with post-tensioning strands and free column ends is conducted. For analysis purposes, a reinforced-concrete building with shear walls was designed, modeled, and analyzed in ETABS software. Nonlinear boundary time history analysis (NTHA) was conducted by exposi...
